英文摘要：

The photoelectro-reactors were introduced from two types of slurry photoelectro-reactor and immobile photoelectro-reactor. An effective way of modifying photo-electrode by deposition of metal and coupling of semiconductor used to improve the oxidation efficiency of immobile photoelectro - reactor was pointed out. The main factors, including light source, material, additional applied potential, solution condition and reaction atmosphere, which affected the efficiency of photoelectro-reactor were discussed. Besides, some proposals for further studies of photoelectro-reactor were presented.
